Vetting Ambiguous Planetary Candidates (APC) in TESS Data: Insights from LATTE Package and Detection of Nine Potential Exoplanet Candidates

Abstract

We present the results of our study of Ambiguous Planetary Candidates (APCs) in data from the Transiting Exoplanet Survey Satellite (TESS) using the open-source LATTE package. LATTE provides an effective framework for distinguishing transit-like signals, including planetary candidates and eclipsing binaries, from stellar variability and instrumental noise. We performed a comprehensive analysis of TESS APCs by applying the LATTE diagnostic tools and visually inspecting the resulting light curves and diagnostic plots to identify false alarms and false positives. Our analysis confirms nine potential exoplanet candidates that warrant follow-up observations with ground-based facilities. These findings demonstrate the effectiveness of the LATTE package for the identification and vetting of exoplanet candidates in TESS data. Future analyses incorporating observations from additional TESS sectors will further improve candidate validation and may lead to the discovery of additional exoplanet candidates.
